In his message to Esau, Jacob tells Esau that he lived with Laban and adds:
Genesis 32:6
“וַיְהִי-לִי שׁוֹר וַחֲמוֹר, צֹאן וְעֶבֶד וְשִׁפְחָה; וָאֶשְׁלְחָה לְהַגִּיד לַאדֹנִי, לִמְצֹא-חֵן בְּעֵינֶיךָ”
“I have oxen, donkeys, flocks, male servants, and female servants. I have sent to tell my lord, in order that I may find favor in your sight.”
